Tools

• delete_chart Deletes data · ~127 tokens
  Use this when the user explicitly wants to permanently delete one saved chart. Deletion cannot be undone, and retrying an already completed deletion succeeds; requires authentication.
• get_chart ~134 tokens
  Use this when the user identifies a saved chart by id and wants to view it or retrieve its metadata and URLs. Displays the published chart when available and does not return its document; requires authentication.
• get_chart_document ~130 tokens
  Use this when the user identifies a saved chart by id and needs its complete published Szum document for inspection or reuse. Does not return a newer editor draft; requires authentication.
• get_examples ~499 tokens
  Get complete Szum documents for validation, rendering, or saving, with guidance on when to use each pattern. No filters returns one starter per chart type. Any filter searches the complete catalog; all supplied filters intersect. Most data is illustrative; the Vinyl waterfall cites RIAA reports. Emp
• get_preview_state ~133 tokens
  Use this when the Szum chart App needs to restore a rendered preview as its current transient or saved view. It is read-only, owner-scoped when authenticated, and hidden from the model.
• get_schema ~227 tokens
  Use this before authoring an unfamiliar field instead of probing validate_chart for errors. Returns the JSON Schema for the whole Szum document, covering config, data, presentation, size, and output, with every referenced definition included. Pass chart_type to keep only that family's config variant
• list_chart_types ~60 tokens
  Use this when choosing a chart family. Returns every current chart type with its shared and family-specific fields.
• list_charts ~384 tokens
  Use this when the user wants to find charts in their saved library. Returns paginated metadata and URLs, not chart documents; requires authentication. Draft-only editor charts have publishedAt null, hasDraft true, and sizeBytes 0 because sizeBytes measures only the stored published document, not dra
• list_themes ~74 tokens
  Use this when choosing a visual theme for a chart. Returns every built-in theme with guidance on where each works best and, when signed in, the workspace's shared themes.
• rename_chart ~152 tokens
  Use this when the user wants to change a saved chart's library title without changing its document, publication state, or public URLs; requires authentication.
• render_chart ~625 tokens
  Use this when the user wants to preview or generate a chart. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors block; warnings require explicit user approv
• save_chart ~700 tokens
  Use this when the user wants to permanently save and publish a Szum chart document. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors block; warnings requi
• update_chart ~755 tokens
  Use this when the user wants to replace and publish a saved chart's document while keeping its id and URLs. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Erro
• validate_chart ~422 tokens
